I feel like this song's lyric is about two peoples relationship, and will it be fixed or not depends on if his partner is willing to. This song could be between couples, siblings, between family's, or yourself.
"Do you need, do you need someone" shows someone that is trying to reach out, but "He has done this all before", means that this relationship has gone through its own rough times, and "Will you leave or will you carry on",and "But you're lying, lying to yourself, that he'll find help" is like him asking his partner will you try to make this work (like asking a counselor)or will you move on with someone else.
This song reminds me of, my and my mothers relationship, and how it affects my hole family, and my feelings towards others.
(sorry for any grammar or spelling errors)
